SPECIFICATION forming part of Letters Patent No. 717,411, dated December 30, 1902.

Application filed September 24, 1901. Serial No. 76,392. (No model.)

To 00% whom it may concern:

Be it known that I, OLIN A. JOHNSTON, a citizen of the United States, residing in the city and county of Philadelphia, State of. Pennsylvania, have invented new and useful Improvements in Vaporizers, of which the following is a specification.

My invention relates to a new and useful improved medical device,"which I call a distributer and which is used in combination to form an improved complete vaporizing apparatus, the object of this improved vaporizing apparatus being to provide a simple, inexpening had to the accompanying drawings,'in

which- Figure 1 is a longitudinal sectional view showing my improved vaporizer. Fig. 2 is a plan View of the receptacle. Fig. 3 is a sectional view of distributor adapted to use as an inhaler.

In the practice of my invention I employa receptacle A, (preferably cylindrical in form,) made offglass, rubber, or metal, (preferably of glass,) having one end closed and the other end open. ed on the outer surface to receive a screw-cap D and has a smooth inner surface, which receives a perforated stopper P. Stopper P (preferably of cork or rubber) has two perforations placed slightly apart near the center and extending entirely through it parallel to the axis of receptacle A. Stopper P fits tightly into the mouth oropen end ofreceptacle A.

V is a circular elastic disk, preferably of sheet-rubber, the periphery of which measures the same as the outer periphery of the mouth of receptacle A and has two perforations in line with the perforations in stopper P.

The open end or mouth is threadalso adequately describes the construction of screw-cap I, which fits the screw-threads at Inlet-tube E and outlet-tube F (preferably of glass) each pass through one of the perforations in disk V and through the corresponding perforation in stopper P. The openings, which extend the full length through these tubes E and F, form, respectively, the only means of ingress and egress to and from receptacle A, which is rendered otherwise airtight and liquid-tight when stopper P and disk V are placedin position.

Tubes E and F are of sufficient length and project well into the body of receptacle Aand, passing through the perforations in stopper P and disk V, extend far enough above and outward from diskV to admit of having fixed to them each a flexible tube.

Metal screw-cap D is adapted to the mouth of receptacle A and is screwed on after the stopper P has been fitted into the mouth of receptacle A and after the disk V has been placed flatly upon stopper P. A circular opening X, large enough to encircle both tubes E and F when in position, is left in the center of the top of cap D. Lip T, which forms a part of cap D, holds disk V and also the stopper P firmly in position.

B is a distributer and consists of a hollow cylindrical body (preferably of glass) having a conoidal tapering termination at one end and at the other end a circular opening or mouth, which is screw-threaded on its outer surface to receive ascrew-cap I.

S is an opening at the point or apex of the tapered end T.

The conoidal tapered end T is sufficiently elongated to receive a flexible tube, which is fixed to it.

The foregoing description of screw-cap D the mouth of distributor B and has a circular opening in the top analogous to opening X in cap D. Lip'W on cap I is analogous to lip R on cap D. The width oflip W and the thickness of the circular Wall of distributor B are approximately the same.

Q is a circular pad composed of a circular piece of wire mesh or perforated sheet metal placed between two circular pieces of felt or cloth or other suitable fiber, all of the same diameter, concentrically arranged and riveted together at the center or stitched together with thread. ployed possesses sufficient rigidity, the wire mesh or perforated sheet metal may be omitted from pad Q, or the one inner piece of felt may be omitted, if desired, without departing from the scope of my invention. The periphery of pad Q measures the same as the outer periphery of the threaded end of distributer B, to which it is fixed by placing it flatly on over the open end and then screwing the cap I tightly onto the threaded end of distributer B. The entire outer edge of pad Q is thus gripped tightly and held in proper position between lip W and the end of the circular wall of distributer B.

O is an ordinary, mouthpiece, which has an opening extending entirely through it longitudinally and adapted at one end to receive a flexible tube.

When desired, mouthpiece C may be removed, and in its stead an ordinary air-forcing bulb, havinginlet and outlet valves and well known commercially as an atomizerbnlb, is fitted to the outward end of tube H.

H is a flexible tube one end of which is fixed to mouthpiece (land the other end of which is fixed toinlet-tube E and completes a direct air-passage communicating with the inside of receptacle A from without.

G is another flexible tube, (of any desired length,) one end of which is fixed to outlettube F and the other end of which is fixed to the tapered end of distributer B and cnvelops the opening S, thus establishing a direct airpassage between the inside of cylinder A and the inside of distributer B.

In the operation of my invention the volatile liquid to be administered is placed within the receptacle A, which is supplied with a sponge K (or otherabsorbent material) to absorb and expose an increased surface of the liquid to the action of the air. The liquid may beintroduced directly through the mouth of cylinder A by removing cap D, stopper P, and disk V or through distributer B by removing cap I and pad Q and pouring the liquid into the open distributer B (as a funnel) and allowing the liquid to run downward through hose G and outlet-tube F and into the receptacle A. The liquid being introduced, all parts of the device are then securely and properly adjusted as above specified. The user then places the pad Q flatly upon the surface of any part of his or another persons body to be treated. A current of airis then introduced by blowing into the mouthpiece. It will be readily seen that a current of air thus introduced is forced through the flexible tube H and inlet-tube E into the cylinder A, where it agitates and becomes thoroughly impregnated With the volatile portion of the liquid used and in thisimpregnated condition is driven outwardly through outlet-tube F, flexible tube G, and into distributer B,whence its only avenue of escape is through the porous surface of pad Q, which evenly distributes the liquid in its minutely-atomized or If the felt or cloth emaeriform condition over as great a surface of the body as is desired by simply sliding the felt pad from spot to spot, the intensity of the application being regulated by the amount of air-pressure given through mouthpiece C. When desired, the same practical results are obtained by employing the before-mentioned ordinary air-forcing bulbinstead of mouthpiece 0 to provide the necessary current of air.

Distributer B, fitted with cap I and pad Q, may be detached from the remainder of the device and used independently thereof as an inhaler by placing the open port S to the nostrils, proper vent being given through the felt pad Q at the other end of the distributer.

Distributer B is adapted when used as an inhaler to receive the desired medicament either in liquid form or solids, (such as menthol.) In case a liquid is used distributer B has fitted into it a sponge L (or other suitable absorbent material) for the purpose of absorbing, retaining, and rendering more readily volatile the liquid used.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a vaporizer the combination of a receptacle A having an externally-screw-threaded mouth, absorbent material placed within receptacle A, a perforated stopper P fitted in the mouth of receptacle A, a perforated elastic disk V, inlet-tube E and outlet-tube F which pass through the perforations in stopper P and disk V and project inwardly and outwardly and form the only means of ingress and egress to and from receptacle A; a screwcap D adapted to'the mouth of receptacle A and having a circular opening X which encircles the outward projections of tubes E and F; a lip R which forms a part of cap D and serves to hold stopper P and disk V in position; a vapor-distributer B consisting of a hollow cylindrical body tapered at one end to an opening S and the other end having a mouth externally screw-threaded; a cap I adapted to the mouth of distributer B and having a circular opening in the top with a lip W extending all around it; a circular felt pad Q which covers the opening at the threaded end of distributer B and is retained in position by lip W of cap I; a flexible tube G, one end of which is fixed to the tapered end of distributer B and the other end of which is fixed to outlet-tube F; a mouthpiece C; a flexible tube H one end of which is fixed to inlet-tube E and the other end fixed to mouthpiece O,substantially as shown and described.

2. In a vaporizer, the combination of a receptacle A, a sponge K, a stopper P, a disk V, a cap D with openings X and a lip R, an air-inlet tube E, an outlet-tube F, a distributer B, a pad Q, a cap I having a circular opening in the top and a lip W, and a flexible tube G connecting the distributer with the tube F, substantially as described.

3. In a vaporizer, a distributer consisting of a hollow body open at both ends, a flat discan be placed in contact with the surface of the body to be treated, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two wit- 15 nesses.
